Simrit 56x80x13/14.5 NBR KASSETTE - RWDR-K7 Cassette Shaft Seal

Overview

Simrit 56x80x13/14.5 NBR KASSETTE RWDR-K7 is a specialized cassette-type radial shaft seal designed for demanding mechanical applications where effective lubricant retention and enhanced protection against external contamination are required.

The seal has a nominal 56 mm inside diameter, 80 mm outside diameter and 13/14.5 mm width. Its sealing components are manufactured from NBR - Nitrile Butadiene Rubber.

The RWDR-K7 KASSETTE design provides a more extensive sealing and protective arrangement than a conventional radial oil seal, making it particularly relevant to mechanisms exposed to dust, dirt, soil, mud and other contaminants.

RWDR-K7 KASSETTE Design

The RWDR-K7 designation identifies the specific construction of this cassette-type shaft sealing system.

Unlike a basic radial oil seal, the KASSETTE design provides an integrated sealing arrangement combining the primary shaft sealing function with additional protection of the working area against external contaminants.

When selecting a replacement, the RWDR-K7 designation should be verified together with the dimensions, as identical shaft and housing diameters alone do not guarantee constructional compatibility.

56x80x13/14.5 mm Dimensions

The principal dimensions are:

d: 56 mm
D: 80 mm
B: 13/14.5 mm

The nominal inside diameter is 56 mm, while the outside diameter is 80 mm.

The complete 13/14.5 mm width specification is an important identification parameter associated with the cassette seal geometry.

When comparing replacement seals, the complete 56x80x13/14.5 mm RWDR-K7 specification should be checked.

NBR - Nitrile Butadiene Rubber

NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers in industrial shaft sealing technology.

It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids.

NBR is therefore commonly used in sealing systems for gearboxes, drive assemblies, hubs, axles and other lubricated mechanical systems.

Final suitability depends on the operating medium, temperature, rotational speed and actual application conditions.

KASSETTE vs Standard Oil Seal

A conventional radial oil seal typically provides dynamic sealing between a rotating shaft and stationary housing.

The Simrit RWDR-K7 KASSETTE incorporates a more extensive integrated sealing system designed to provide additional protection of the primary sealing area against external contamination.

For this reason, a standard 56x80 oil seal should not automatically be considered an interchangeable replacement for the 56x80x13/14.5 RWDR-K7 version.

Applications

FAQ

What are the dimensions of the Simrit RWDR-K7 seal?

The nominal dimensions are 56x80x13/14.5 mm, corresponding to a 56 mm inside diameter, 80 mm outside diameter and 13/14.5 mm width.

What does RWDR-K7 mean?

RWDR-K7 identifies the construction of this cassette-type shaft sealing system. The design designation should be checked together with the dimensions when selecting a replacement.

What does the 13/14.5 mm width designation mean?

It represents the complete width specification associated with the geometry of the cassette seal. The full 13/14.5 mm designation should be retained when identifying a replacement.

What material is the Simrit RWDR-K7 made from?

The sealing components are manufactured from NBR - Nitrile Butadiene Rubber.

What shaft diameter is this seal designed for?

The nominal inside diameter is 56 mm, while the outside diameter is 80 mm.

Is RWDR-K7 a standard radial oil seal?

No. RWDR-K7 KASSETTE is a more extensive cassette-type shaft sealing construction designed to provide additional environmental protection.

Can a standard 56x80 oil seal replace the Simrit RWDR-K7?

Not automatically. The complete 56x80x13/14.5 mm dimensions, RWDR-K7 construction and specific application requirements should be verified before selecting a replacement.
